In Australia May 16, 1944 2 Claims. (01. 100-12) This invention relates to presses for W001 and the like whereby the latter may bev compressed into bales or the like in a rectangular box-like body above which a compressing head or monkey is mounted for reciprocable movement with relation to the body.

In presses of this type various means have been adopted so that in the upward position of the monkey, the latter may be moved sideways to give free access to the body of the press when placing the wool in the body. during each compressing operation.

It has been proposed to mount the monkey upon rack members slidable in pivoted fittings on each of two opposite sides of the body of the press. It has also been proposed to mount the monkey upon a triangular framework loosely connected to a lever pivoted to the body of the press in such manner that the frame with the monkey attached is swung clear of the top of the press.

This latter construction has the disadvantage that when a system of pulleys and cable operated by a winch drum are used the cables require to be slackened before swinging the monkey clear of the body by means of the pivoted lever. Furthermore, the cables owing to such slackness often require to be replaced upon the usual pulleys before a further compressing movement of the monkey can be made.

An object of the present invention is to provide a box body type of press which is free from the above disadvantages, is simple and quick in operation, is not costly to manufacture compared with the more complicated types of presses already upon the market and provides a clear top opening which facilitates loading of the wool or the like into the body.

The present invention, in common with most wool presses of this type, has a box-like body with sides capable of being opened out when it is desired to withdraw the compressed bale of wool or the like. The box-like body rests upon a base board and is open at the top.

Above the open top a monkey or compressor is mounted in such manner that it may be drawn down upon the Wool in the body by a system of pulleys and a cable. Alternatively the monkey may be forced down by other mechanical means such as one or more hydraulic rams.

It has been found that the most convenient way to mount the monkey is upon the end of a ver-' tically movable member or members slidable in a crosshead which is mounted upon pivoted supports disposed on two of the four sides of, the

body. The vertically movable member, or members, henceforthreferred to as a vertically 'movable member, is freely connected to the monkey so that the latter may tilt slightly to provide for slight irregularity in the packing of the wool into the press body during the filling operation; It will be appreciated that the monkey and the vertically movable member are capable of movement relatively to the crosshead as distinct from the known type referred to'above wherein the monkey and its triangular frame float, as it were, with relation to the box body and have no connection with a cross head asa guiding and support-- ing means for the monkey. 1 f In the present invention the monkey is either drawn down by a cable wound upon a winch drum or by other approved means including a mechanically or power operated ram. The monkey and its supporting crosshead and associated mechanism, according to the present invention, when elevated, is capable of being displaced sideways in reference to the press body to provide free access thereto, by mounting the sup ports for the crossheadpivotally at their base so that by applying a transverse movement to the said supports the whole of the cross head and its associated parts are swung clear of the top of the body without afiecting the position of the monkey and its operating and supporting means relatively to the crosshead and the supports therefor.-

The pivoting means for the crosshead supports are disposed in a position off-set to the central vertical axis of two of the sides of the press so that when the said supports are moved to the filling position maximum clearance is provided at the top of the body for loading.

Owing, to the movement of the vertical supe ports about their pivots a latch is provided to retain the said supports with respect to the body during the compressing act. A stop or projection should also be provided on the body or some partassociated. therewith to engage the supports and limit their movement when in their inoperative position. Y

'In order that the invention may be more readily understood reference will now be made to the accompanying drawings wherein- Figure 1 is a front elevational view of the bodyof a press in accordance with the present invention. V

Figure 2 is a side elevational view thereof showing the off-set pivoting of the supports for the crosshead.

Figure 3 is an enlarged .detail rear view of part of the press showing the upper ends of the sun-1v 3 ports and the crosshead and monkey carried thereby.

Figure 4 is a plan view of the structure illustrated in Figure 1.

The press has a box-like body comprising sides 10 and H; front t2: and: rear l-3=held to ether by long pins. l Lpassed through strappingslioflanglo iron which overlap at the corners. The respective sides, front and rear I to l3 inclusive area supported upon a base I6 and the front l2 and side H are capable of being opened out about the pins M, to remove the baleaiten moving; the;

The hooks 30 engage the downturned end portions of the pack and hold them during the compressing act and may be turned in an arcuate manner into and out of engagement with the saidlwooipaclneasily by movementlyof the handles 33. In. the b preferred practice, the pack referred to is in the form of a bag of a size substantially filling the box-like body press locking clamp braoketzQztmthe .un-lookechl os sition.
